This annual survey of employers provides a detailed look at trends in employer-sponsored health coverage, including premiums, employee contributions, cost-sharing provisions, and other relevant information. The survey continued to document the prevalence of high-deductible health plans associated with a savings option and included new questions on health risk assessments. The 2009 survey included 3,188 randomly selected public and private firms with three or more employees (2,054 of which responded to the full survey and 1,134 of which responded to an additional question about offering coverage). Researchers at the Kaiser Family Foundation, the National Opinion Research Center at the University of Chicago, and Health Research & Educational Trust designed and analyzed the survey.
